Hi all, to make my question simple, i am trying to achieve a project something like this: 

 

youtube.com/watch?v=DUGJDoIll10&list=FLtbuyvn-AtYnDBHmBZ_QAMw&feature=mh_lolz 

 

My past experience in verilog is doing Altera lab manual such as adder,counter,fsm,lcd display and so on using Altera DE2 board with Quartus 7. 

 

Past a couple of month before i found out about Quartus 11.1 not having an internal vector waveform makes me learn to write the testbench using modelsim. 

 

Now i have successfully produce a sine wave in modelsim using simple method of counter and a LUT. I also know that we can generate that signal using NCO IP and have succesfully generate the waveform. 

 

Next is i need help on displaying this signal on a vga display. My only knowledge is the only altera control panel tools where it can display image in SRAM and control the horizontal and vertical line. 

 

Can someone kindly point out quick and easy step for me to display the sine wave to vga. I found out that i took a long time to search and learn it by myself. Thanks for reading this and your reply is highly appreciated.

Yes, i still figuring out on how to assign my output signal to vga RGB pin and the horizontal and vertical coordinates.  

 

As an example i have this single output which produce a see saw signal. The output is a 10 bit length from 16bit counter.
